I have a map that I'm using in Collector for playground inspections. Each piece of equipment needs to be inspected numerous times in a year. Each inspection is stored in a related table. For the popup on the playground equipment I configured so that is displays the number of inspection using the statistic operator

This works as expected in AGOL

However in collector the field is always blank. Is this not supported in Collector or have I sent up things incorrectly?
